You need to form a package wrapper with Aluminium foil over a product. The
dimensions of the Aluminium foil required is 200mm x 200mm for 1 product. One
roll of Al foil purchased has 500metres of foil of 250mm width. Cost of 1 Roll of this
Al foli is Rs. 10,000/-. Since you need to wrap 1,00,000 products automatically in
the machines. Calculate the cost of Al foil to be purchased.
1. Calculate the foil requirement for 1 lakh products
2. Calculate number of foll rolls required.
3. Calculate the cost of Al foil to be purchased.

Answer:
Aluminium foil (or aluminum foil in North America; often incorrectly called tin foil) is aluminium prepared in thin metal leaves with a thickness less than 0.2 mm (7.9 mils); thinner gauges down to 6 micrometres (0.24 mils) are also commonly used.[1] In the United States, foils are commonly measured in thousandths of an inch or mils. Standard household foil is typically 0.016 mm (0.63 mils) thick, and heavy duty household foil is typically 0.024 mm (0.94 mils). The foil is pliable, and can be readily bent or wrapped around objects. Thin foils are fragile and are sometimes laminated with other materials such as plastics or paper to make them stronger and more useful. Aluminium foil supplanted tin foil in the mid 20th century.
A roll of aluminium foil
Annual production of aluminium foil was approximately 800,000 tonnes (880,000 tons) in Europe[1] and 600,000 tonnes (660,000 tons) in the U.S. in 2003.[2] Approximately 75% of aluminium foil is used for packaging of foods, cosmetics, and chemical products, and 25% is used for industrial applications (e.g., thermal insulation, electrical cables, and electronics).[2] It can be easily recycled.
In North America aluminium foil was popularised by Reynolds Metals, the leading manufacturer in North America. In the United Kingdom and United States it is, informally, widely called tin foil, for historical reasons (similar to how steel cans are often still called "tin cans"). Metallised films are sometimes mistaken for aluminium foil, but are actually polymer films coated with a thin layer of aluminium. In Australia, aluminium foil is widely called alfoil.
